A GtkIconSource contains a (or image
filename) that serves as the base image for one or more of the
icons in a , along with a
specification for which icons in the icon set will be based on
that pixbuf or image file. An icon set contains a set of icons
that represent the same logical concept in different states,
different global text directions, and different sizes.
A contains a (or image
filename) that serves as the base image for one or more of the
icons in a , along with a
specification for which icons in the icon set will be based on
that pixbuf or image file. An icon set contains a set of icons
that represent the same logical concept in different states,
different global text directions, and different sizes.
So for example a web browser's "Back to Previous Page" icon
might point in a different direction in Hebrew and in English;
it might look different when insensitive; and it might change
size depending on toolbar mode (small/large icons). So a
single icon set would contain all those variants of the
icon. contains a list of from which
it can derive specific icon variants in the set.
In the simplest case, contains
one source pixbuf from which it derives all variants. The
constructor handles
this case; if you only have one source pixbuf, just use that
function.
If you want to use a different base pixbuf for different icon
variants, you create multiple icon sources, mark which
variants they'll be used to create, and add them to the icon
set with .
By default, the icon source has all parameters
wildcarded. That is, the icon source will be used as the base
icon for any desired text direction, widget state, or icon
size.
GLib.OpaqueMethodGtk.IconSource
Creates a copy of the current ; mostly useful for language
bindings.
a new GtkIconSource that is a copy of the current one
MethodSystem.VoidFrees a dynamically-allocated icon source, along with its filename, size, and pixbuf fields.ConstructorInternal constructor
Pointer to the C object.
This is an internal constructor, and should not be used by user code.ConstructorCreates a new .PropertySystem.Boolean
If the widget state is wildcarded, this source can be used
as the base image for an icon in any .
Whether or not the widget is wildcarded.
If the widget state is wildcarded, this source can be used
as the base image for an icon in any . If the
widget state is not wildcarded, then the state the source
applies to should be set with
and the icon source will only be used with that specific
state.
prefers non-wildcarded
sources (exact matches) over wildcarded sources, and will
use an exact match when possible.
will normally transform
wildcarded source images to produce an appropriate icon
for a given state, for example lightening an image on
prelight, but will not modify source images that match
exactly.
PropertySystem.Boolean
If the icon size is wildcarded, this source can be used as
the base image for an icon of any size. If the size is not
wildcarded, then the size the source applies to should be
set with and the icon
source will only be used with that specific size.
Whether the size is wildcarded or not
If the icon size is wildcarded, this source can be used as
the base image for an icon of any size. If the size is not
wildcarded, then the size the source applies to should be
set with and the icon
source will only be used with that specific size.
prefers non-wildcarded
sources (exact matches) over wildcarded sources, and will
use an exact match when possible.
will normally scale
wildcarded source images to produce an appropriate icon at
a given size, but will not change the size of source
images that match exactly.
PropertyGdk.Pixbuf
The base image used when creating icon variants of a the source pixbuf, or if none is set.
If an icon source has both a filename and a pixbuf set, the
pixbuf will take priority.
PropertyGtk.TextDirection
The text direction this icon source applies to.
Obtains the text direction this icon source applies to. The
return value is only useful/meaningful if the text direction
is not wildcarded.
Setting the text direction on an icon source makes no
difference if the text direction is wildcarded. Therefore,
you should usually set the property to
un-wildcard it in addition to calling this function.
PropertyGtk.IconSize
The icon size this icon source is intended to be used with.
Obtains the icon size this source applies to. The return
value is only useful/meaningful if the icon size is not
wildcarded.
Setting the icon size on an icon source makes no difference
if the size is wildcarded. Therefore, you should usually set
the property
to un-wildcard it in addition to calling this function.
PropertyGtk.StateType
The widget state this icon source applies to.
Obtains the widget state this icon source applies to. The
return value is only useful/meaningful if the widget state
is not wildcarded.
Setting the widget state on an icon source makes no
difference if the state is wildcarded. Therefore, you should
usually set the propertyto un-wildcard it in addition to calling this
function.
PropertySystem.Boolean
If the text direction is wildcarded, this source can be used
as the base image for an icon in any .
Whether the text direction is wildcarded or not
If the text direction is wildcarded, this source can be
used as the base image for an icon in any . If the text direction is
not wildcarded, then the text direction the icon source
applies to should be set with , and the icon source
will only be used with that text direction.

sources (exact matches) over wildcarded sources, and will
use an exact match when possible.
PropertySystem.String
Retrieves the source filename, or if none is set.
Retrieves the source filename, or if
none is set. The filename is not a copy, and should not be
modified or expected to persist beyond the lifetime of the
icon source.
